title: [Extraction rate of trace elements in wuling san in simulated gastric fluid].
abstract: The present paper reports the determination of twelve trace elements in Wuling San and its extracts in simulated gastric fluid by atomic absorption spectroscopy. The experimental result shows that among these elements the extraction rate of K, Na and Mn is higher in extracts of Wuling San, and that of the other nine elements differs greatly from each other between 4-89%.
